Amendment March 26, 1980 The scope of claims for utility model registration is amended as follows. O Utility Model Registration Claims: An adjustment bolt and an adjustment bolt screwed together with a multi-thread screw in a hydraulic pressure chamber defined by a viston that is fluid-tightly and movably fitted into a wheel cylinder and its opposing part. A nut is disposed, the clutch portion of the adjusting nut is brought into contact with a clutch surface formed on the opposing portion, and the south adjusting nut is connected to a communicating portion formed on a flange portion defining a cup chamber of the piston. A hydraulically operated type in which rotation is restricted by a plurality of legs of a retainer hooked in the hole, and the end surface of the adjuster is brought into contact with the flange of the piston by a spring compressed between the retainer and the adjuster nut. In the brake braking gap automatic adjustment device, the retainer has a bifurcated shape in which a hook is formed at the tip of a leg bent from the periphery of the annular head, and a notch is provided at the tip of the leg. An automatic braking gap adjustment device for hydraulically operated brakes, which is characterized by: ′
